Lɔ̈ɔ̈ŋ:

Municipal Sludge: High organic content, hydrophilic requires high-charge-density CPAM.

Industrial Sludge (cït mɛn, electroplating, papermaking): Lëu bï ya tɔ̈u në metal ye kɔc cɔl heavy metals ka inorganics.

pH wɛ̈t:

Acidic (pH < 7): A prefer non-ionic wala low-charge CPAM.

Low charge (5-10%): For inorganic sludge or pre-conditioning.

4. Kä ye kek looi

Centrifuge: Medium-high charge density, medium-high MW CPAM for fast flocculation.

Belt Filter Press: High MW, medium-high charge CPAM for shear-resistant flocs.

Plate-and-Frame Filter: Low MW, low charge CPAM/APAM to prevent clogging.
